Are They Or Aren’t They? Mark Salling Kisses ‘Glee’ Co-Star Naya Rivera- Then Checks Out Other Girls!

Don’t worry, ladies – Mark is still on the market! Just because he makes out with his co-star DOESN’T mean he’s ready to be a BF!

Mark Salling isn’t ready to put a label on his relationship with Naya Rivera. We caught the super-stud making out with his Glee co-star at the Chateau Marmont in Hollywood last night – and then witnessed him checking out other girls!

We caught the 27-year-old star – who plays girl-crazy football player Noah ‘Puck’ Puckerman on Fox’s OTHER hit singing show – intermittently making out with Naya, 23, throughout the evening. But mostly the two did their own separate things. While Naya, who plays sexed-up cheerleader Santana Lopez, walked around with a male pal, Mark shook his moneymaker with a group of dancers and checked out a few good-looking ladies who caught his eye at the famous Hollywood hotspot.

This isn’t the first time we’ve seen Mark and Naya in action. We first suspected they might have a thing when we saw the two getting cozy at the Grey Goose-sponsored SAG Awards afterparty in LA Jan. 23. THEN, when TV Guide reported the two were a couple March 9, we let you know that they are, in fact, just dating.

Although we’d love for Mark to stay single (for obvious reasons) we have to wonder how Naya puts up with his behavior. He can’t have his cake AND eat it, too!
